158    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
159 
160    Not Collective
161 
162    Input Parameters:
163 +  name - name of a new user-defined matrix type
164 .  path - path (either absolute or relative) the library containing this solver
165 .  name_create - name of routine to create method context
166 -  routine_create - routine to create method context
167 
168    Notes:
169    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
170 
171    If dynamic libraries are used, then the fourth input argument (routine_create)
172    is ignored.
173 
174    Sample usage:
175 .vb
176    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
177                "MyMatCreate",MyMatCreate);
178 .ve
179 
180    Then, your solver can be chosen with the procedural interface via
181 $     MatSetType(Mat,"my_mat")
182    or at runtime via the option
183 $     -mat_type my_mat

186 
187    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
188          If your function is not being put into a shared library then use VecRegister() instead

1595 
1596    Not Collective
1597 
1598    Input Parameters:
1599 +  name_solver - name of a new user-defined compute-h module
1600 .  path - path (either absolute or relative) the library containing this solver
1601 .  name_create - name of routine to create method context
1602 -  routine_create - routine to create method context
1603 
1604    Level: developer
1605 
1606    Notes:
1607    MatMFFDRegisterDynamic() may be called multiple times to add several user-defined solvers.
1608 
1609    If dynamic libraries are used, then the fourth input argument (routine_create)
1610    is ignored.
1611 
1612    Sample usage:
1613 .vb
1614    MatMFFDRegisterDynamic("my_h",/home/username/my_lib/lib/libO/solaris/mylib.a,
1615                "MyHCreate",MyHCreate);
1616 .ve
1617 
1618    Then, your solver can be chosen with the procedural interface via
1619 $     MatMFFDSetType(mfctx,"my_h")
1620    or at runtime via the option
1621 $     -snes_mf_type my_h
